The question is, how could you update SotN with much added QA?
This one's easy.
Language Options, New/Old translation, Japanese dubs
Volume Slider for SFX/BGM/Voices
Aspect options, Choose between Native, 4:3, or 16:9; The 16:9 will draw more tiles to fill in the screen on horizontal areas (See the PC port of Chrono Trigger to see what I mean)
Quick Spells; Right Analog can be utilized to quick cast spells on the fly a la Blazblue.
Better Organization of Items/Equipment utilizing tabbed browsing, mark a favorite ect.
Map Overhaul; Add option to add markers for returns, color areas to make them distinguishable.
Better Portraits, Rondo Richter for Prologue, all higher res, ect.
Fixed Resolutions and Z-axis for all Polygonal objects; make them fit in a 2D enviornment better.
Re-touched Spritework all-around; Richter needs an upgrade, a few enemies could use more than a few key-frames.
Add the Saturn Content! Just do it, Allow the player to experience BOTH Maria styles and choose which Richter was Stylin'
Difficulty Options, Spice things up a bit, the ol' Berserk challenge is fun.
re-arranged Inverted Castle, Maybe something for those who wish for a hard mode.
Netflix Alt. Costumes, because Konami forgot how to properly fanservice.
Yeah, sure add all those Requiem "updates" too.
I'd buy that for $30.
